I'AYP FOR BEER-BARRELS.

' SPECIFICATION forming part of llietters- Patent No. 729,545, datedJune 2, 1903 Applieationiiled January '7, `1.903.

To all whom it may concern;

Be itknown that LMANLEY J. CHAPLIN, a citizen of the UnitedStatesesiding at Seattle, in the county of King and Stateef Washington, haveinvented certain new and useful Improvements in Taps for Beer-Barrels,of which the following is a specification, refer` ence being had thereintothe accompanying drawings. p Y

This invention has relation to improvements in beer-barrel taps; and itconsists in the construction, novel arrangement, and adaptation ofdevices, as will be hereinafter more fully described and claimed.

The object of theinvention is the perfection of a tap for use on or withany beer-barrel. This object I accomplish by the means shown andillustrated in the accompanyingv drawings, in Whichp Y Figure l is acentral longitudinal section through a barrel-tap embodying my inven-Fig. 2 is a similar view oflthe socket shown in Fig. 1 with thebung-stopper in place. Fig. Sis a view of Fig. 2, taken in the directionindicated by arrows y. Fig. 4 is a perspective view of part ofthe'draw-tube casing.

Referring tothesaid drawings, the letter A represents a bung-sockethaving an external screw-thread, as shown at et, for securing the samein the bulge or head H of the beer barrel or cask to which the inventionis applied.- The socket is provided at one end with a contractedcylindrical opening b, for the'reeeption of a cork stopper s, andterminating inperipheral shoulder b'. The other end of the socket isformed with oppositely-arranged-V longitudinal slots C, which terminateinte! riorly of the socket in transverse obliqueshelves c. L Y

D indicates a cham bered casing, preferably made of twopartscd and d',integrally coupled by screw-threads c and a set-screw e. v`Ad-vA jacentto one end of the casing part-d' are latorally-projecting stndsf,adapted to be entered'into the aforesaid slots.

gis a circular offset, having at its periphery a downwardly-extendingfiange g to provide an annular cavity h to receive a washer W.

d" denotes a bos's integral with the outer part d of the casing, inwhich is screwed a serai No. 138,116. (No modil) nipple z' for'makingconnection by a flexible pipe with the usual air-supply pump.

T is a cylindrical draw-tube, which is connected in any suitablevmannerwith a faucet and is externally of. lessdiameter than the saidcontractedopening ofthe socket and also the reduced opening 7o ofgthecasing.

Under the last-named openingis a shoulder lo', against whichV is placeda packing ring or washerL for making a tight joint around the draw-tube.Interiorly ofV the casing is a sleeve M of greater internal diameterthan is the said draw-tube and ofa length greaterl than the distancebetweenthe socket-shoulder bA and the face Z of the Washer L when thecasing studs f have. engaged the said shelves c'. '-7 Y N is abelt-channelv Asurrounding the 'said sleeve opposite to the air-inletopening of boss d, to which communication is made with the inside of'thesleeve by apertures n, whereby air is admitted to the barrel.

. The operationof theinventiomwill now be described, reference Ybeingmade to Fig. l. 75 The socket being supposed to'be inserted in l thebung-hole and closed bya stopper, (shown by broken lines,) the.casingcontaining the afore-described-sleeve and washers W and L is enteredinto the socket by passing the projecting studs f through the slotsthereof and upon being partially rotated is caught by studs, and thesaid washers are slightly compressed. The drawtube is now insertedthrough the casing and its sleeve, dislodging fthe said stopper, andwhen in the required position the casing is rotated until stopped by oneof the said studs being intercepted in its travel by a lug m, duringwhich turningv the casing is obviously drawn into the socket, furthercompressing the washer W and through theinterposition of the sleeve theother washer, L, thus not only making non- ;leakable joints thereat, butalso locking the IDO an opening extending therethrough which is reducedat one end and terminates at a shoulder b intermediate said opening,oppositelyarranged longitudinal slots at the other end of socketterminating in oblique shelves internal of the socket, a casing havingexternal projecting studs adapted to be entered said slots and providedwith a cylindrical chamber having a shoulder 7c' at its outer end, anexternal off-set cavity 7L surrounding said casing, a perforated sleeveof greater internal diameter than the said tube and extending from theshoulder b' of the socket to within a short distance of the chamber end7c of the casing, and communicative connection between the saidperforations of the sleeve and a source of air-supply, substantially asand for the purposes set forth.

2. In a device of the character set forth, the combination with adraw-tu be, a bung-socket provided with an internal shoulderintermediate its length, a casing adapted to be entered said socket andmeans for drawing the same into and engaging with the said socket byrotating the casing, and communicative connection between the inside ofsaid casing and the source of air-supply; of an annular Washer externalof and carried by the casing and adapted to bear against the saidsocket, a Washer positioned at the outer end of the chamber of thecasing, and a sleeve extending from, outside the inner end of the casingto the last-named washer, whereby it is compressed simultaneously withthe other washer and the coupling of the casing with socket,substantially as described.

3. In a device of the character described, the combination with thesocket, a chambered casing provided with an air-inlet, a drawtubeextending axially through said casing and said socket; of a perforatedsleeve surrounding said tube so as to provide an annular passagetherebetween the entire length of the sleeve, said sleeve extending fromoutside the inner end of the casing to Within a short distance from theshoulder at the outer end of the chamber of said casing, andcommunication between said passage and the said airinlet of the casing,substantiallyas described.

In testimony whereof I affix my signature in presence of two witnesses.
